    摘要： Quality feedback in a streaming service wherein at least one media stream (101) is streamed to a client (601) and a quality feedback value is determined (304) according to at least one quality metric is improved by determining (305) a timestamp relating to said quality feedback value according to at least one timestamp metric, wherein for each of said at least one quality metrics, a corresponding timestamp metric is defined, and wherein each of said at least one timestamp metrics is based on a relative media playback time of said at least one media stream (101), and reporting (306) said quality feedback value and said related timestamp to a server (600). Said relative media playback time is preferably derived from RTP (102) timestamps, from a NPT provided by a RTSP (109), from timestamps of a RTCP or from timestamps of a SIP.
